MissSongBird:
Don't be discouraged. As a general rule most quilters are genuinely nice, accepting people. I am the youngest in my group of about 15 women (just turned 35). Most of the ladies are over 50, but we have all bonded. One of the ladies son (who is my age) actually asks her why Jennifer (me) would want to hang out with a bunch of old women
I just joined the Modern Quilt Guild here in Portland. The members of this guild tend to be younger. Might I suggest seeing if you have a local modern quilt guild you can join?
Happy Quilting!
